Air France 447 crash mystery deepens as black box signal is deemed false

The French newspaper Le Monde reported that faint beacon signals that the black box emits every second for up to thirty days was detected by the French navy vessels searching for the black box.

The conflicting reports caused confusion given the serious implications of locating and recovering the black box. However, these reports proved to be unfounded as French officials confirmed that the signals were not from the Air France 447 black box.

The reports were confirmed by a close aid to Jean-Louis Borloo, the head of the French transport ministry.

The aide to the transport chief said "black boxes have not been detected," and added that some sounds were heard underwater by the ships scouring the area for the black box but these proved to be false.

The Airbus A330 carrying 228 people disappeared from the radar on its way from Rio de Janeiro to Paris. All 228 passengers and crew onboard are presumed dead and so far, only 50 of the bodies were recovered from the Ocean.

The investigators have pleaded for patience as they swift through the 400 plus debris of the Air France flight that crashed.

Unless the black box is recovered the investigators face a daunting task in solving the mystery.

The French authorities have warned that the black box of the flight may never be found and it was a race against time to locate and recover the device before the battery powering the beacon "pingers" signal fades off.
